PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

FADS2‐STING Signaling in Sertoli Cells Orchestrates Collagen Deposition and Germ Cell Necroptosis in Idiopathic Non‐Obstructive Azoospermia

open access: yesAdvanced Science, EarlyView.
In Sertoli cells of iNOA testes, downregulation of FADS2 activates STING, promoting collagen deposition and peritubular fibrosis while increasing germ‐cell susceptibility to necroptosis. Supplementation with FADS2‐derived PUFAs (GLA and DHA) inhibits STING, alleviates collagen accumulation, and facilitates the recovery of spermatogenesis.

Cardiac Endothelial Enhancer RNA Tek‐e1 Restores Microvascular Homeostasis After Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
Hypoxia‐induced KDM5A downregulation establishes a distinct endothelial repair programme, increasing H3K4me3 at the Tek promoter and intronic enhancer, enabling ISL1 to coordinately activate Tek transcription and induce enhancer‐RNA Tek‐e1. This cis‐regulatory RNA is essential for additional Tek/TIE2 induction through R‐loop formation and reinforced ...

ALDH2 Deficiency Promotes Mitochondrial Oxidative Stress and Adverse Limb Outcomes via VDAC–HSP60 Signaling

open access: yesAdvanced Science, EarlyView.
ALDH2 deficiency promotes 4‐HNE accumulation, resulting in covalent modification of HSP60, disruption of its oligomeric assembly, and VDAC1‐dependent release of HSP60 from mitochondria to the cytosol. Pharmacological activation of ALDH2 preserves HSP60 proteostasis and mitochondrial integrity, whereas the clinical association between the ALDH2 rs671 ...

Assessing the Impact of Promotions on Consumer Purchasing Behavior During Crises

open access: yesAgribusiness, EarlyView.
ABSTRACT Understanding how households modify their food expenditure decisions during times of crisis is essential because consumer purchasing behavior frequently changes during these times. This study looks at these behavioral shifts during the COVID‐19 pandemic, concentrating on how price sensitivity and response to sales promotions changed over the ...
